Weighing from as little as 2.8lbs (1.27kg), the INOGENONE® G4 really does “punch above its weight” with an incredibly compact, sleek, and stylish design. It is the smallest and lightest portable oxygen concentrator in our range offering 3 pulse flow settings.
The G4 is very quiet and unobtrusive producing noise that is less than a normal indoor conversation. It is simple to operate. The user interface features a white back-lit LCD display that clearly shows the current pulse flow setting as well as the remaining battery life.
When using the G4, its intelligent oxygen delivery system works in accordance to the user’s respiration rate by automatically adjusting how short or long each burst of oxygen is delivered. During the periods of high exertion, the oxygen is delivered in shorter bursts. Whilst sleeping or during periods when respiration is at a lower rate, the G4 will give longer bursts. This clever system will ensure the user maintains the correct dosage of oxygen as prescribed. It comes complete with both mains and car power supply units.

How much does it weigh?
It is ultra-lightweight and easily worn over the shoulder with the provided carry bag and shoulder strap. An optional backpack accessory is available to purchase separately for even greater comfort whilst mobile.
